My invention relates to an improved device. designed for application toand use in combination with the of spinning machines, preventingrollerlaps bottom delivery rolls with the object of or fibre being woundat all times.

The invention comprlses a reciprocating bar on one side of which is feltor other fibrous slidably mounted in spring ings adjacent to the of feltis in rubbing face of the roll and a requlsite amount of pressurebetween the clearer the action of the springs on maintained by thebearlngs.

In the embodiment of the invention shown in the accompanying drawings,it is illustrated as applied to the bottom carrier rolls ,of an ordinaryand worsted spinning in well known type of achine. Inasmuch as theinvention appertains solely to the roll cleaning. device, and asrangement and operation of worsted spinning machines are tion of thelatter is The said roll cleaner well known, no descripdeemed to benecessary.

the spring hangers 15 fixed to the carrier roll bearing brackets 16which are slidably mounted on the roll stands 17 The resiliency of thespring hangers forces the bar into contact with the roll surface,thereby maintaining the latter in a clean condition at all times. Theoperation of cleaning the roll is rendered more effective by imparting areciprocating motion to the bar 10 which I accomplish by suitableconnecting means between the bar and some continuous moving part of themachine, preferably the roving traverse motion commonly used on spinningmachine such as shown in Figure 3, wherein the back drawing roll 18transmits rotary motion to the shaft 19 by means of the worm QO'flXGLlto the roll coacting with the gear 21 to said shaft, the shaft beingsupported in the hanger 22 fixedly connected to the back bar 23 which isbolted to back roll brackets 24 slidably mounted on roll stands 17. Acam 25 fixed to the shaft 19 coacts with the follow roll 26 rotatable ona stud 27 fixed to the roving traverse bar 28 which is slidably mountedin bearings formed in the bases of the back roll brackets 24. The followroll is held in constant con tact with the working surface of the cam bytraverse bar 28 and stationary back bar 23. By this construction theroving traverse bar slides back and forth in its bearings to an extentdetermined by the eccentricity of the ca'm.

In order to impart a reciprocating motion to the clearer bars 10 afinger 3O fastened to the roving traverse bar 28 coacts with a slot 31in the rear end of a lever 32 which is supported on a stud 33 swingablymounted in an ear 34 fixed to the back bar 23. The front end of saidlever coacts with finger 35 in fixed relation with the clearer thetension spring 29 connected between motion of the roving traverse barimparts a like motion to the clearer bar with the result that thesurface of the roll is kept free from lint and oil which if allowed toaccumulate would be detrimental to the quality of yarn being produced.

I claim:

A drawing roll cleaner for spinning machines comprising a bar having astrip of fibrous material affixed thereto in rubbin contact with thesurface of the drawing 1 01f, marable in a atar the has is slid ablymounted, a spring coacting With each bearing to press the bar againstthe surface of the roll, a lever, a fulcrum on which said lever isswingable, a connecting finger between the clearer bar and the lever,and a connection between the lever and the roving traverse bar wherebythe reciprocating movement of the latter actuates the lever and impartsa reciprocating motion to the clearer bar.

In testimony whereof, I have signed this specification.
